Anthurium plant named ‘Red Sensation’

ABSTRACT

A new and distinct cultivar of  Anthurium  plant named ‘Red Sensation’, characterized by its upright and outwardly arching plant form; freely clumping growth habit; medium to dark green-colored leaves; red-colored spathes with pale yellow to red-colored spadices that are positioned above and beyond the foliage on strong and erect scapes; freely flowering habit; and good inflorescence longevity.

Botanical designation: Anthurium hybrida.

Cultivar denomination: ‘Red Sensation’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium hybrida and hereinafter referred to by the name ‘Red Sensation’.

The new Anthurium is the result of a planned breeding program conducted by the Inventors in Chamrajpet, Bangalore, India. The objective of the breeding program is to create new vigorous Anthurium cultivars with compact and dense plant habit, unique leaf coloration, interesting leaf shapes, resistance to pathogens and pests common to Anthuriums and tolerance to low temperatures.

The new Anthurium originated from a cross-pollination made by the Inventors on Jan. 12, 1995 of the Anthurium andreanum cultivar Chilli Red, not patented, as the female, or seed, parent with the Anthurium hybrida cultivar Lady Jane, not patented, as the male, or pollen, parent. The new Anthurium was discovered and selected by the Inventors as a single plant within the progeny of the stated cross-pollination in a controlled environment in Chamrajpet, Bangalore, India.

Asexual propagation of the new cultivar by cuttings since July, 1996 in a controlled environment in Chamrajpet, Bangalore, India, has shown that the unique features of this new Anthurium are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Red Sensation’. These characteristics in combination distinguish ‘Red Sensation’ as a new and distinct cultivar of Anthurium:

-   -   1. Upright and outwardly arching plant form.     -   2. Freely clumping growth habit.     -   3. Medium to dark green-colored leaves.     -   4. Red-colored spathes with pale yellow to red-colored spadices         that are positioned above and beyond the foliage on strong and         erect scapes.     -   5. Freely flowering habit.     -   6. Good inflorescence longevity.

In side-by-side comparisons conducted by the Inventors in Chamrajpet, Bangalore, India, plants of the new Anthurium differed from plants of the female parent, the cultivar Chilli Red, in the following characteristics:

-   -   1. Leaves of plants of the new Anthurium were shorter, not as         cordate and lighter green in color than leaves of plants of the         cultivar Chilli Red.     -   2. Plants of the new Anthurium had smaller spathes than plants         of the cultivar Chilli Red.

In side-by-side comparisons conducted by the Inventors in Chamrajpet, Bangalore, India, plants of the new Anthurium differed from plants of the male parent, the cultivar Lady Jane, in the following characteristics:

-   -   1. Leaves of plants of the new Anthurium were more cordate and         lighter green in color than leaves of plants of the cultivar         Chilli Red.     -   2. Plants of the new Anthurium had larger spathes than plants of         the cultivar Chilli Red.

Plants of the new Anthurium can be compared to plants of the cultivar Red King, disclosed in U.S. Plant Pat. No. 13,381. In side-by-side comparisons conducted in northern Texas, plants of the new Anthurium differed from plants of the Anthurium cultivar Red King in the following characteristics:

-   -   1. Plants of the new Anthurium were smaller than plants of the         cultivar Red King.     -   2. Leaves of plants of the new Anthurium were smaller and         lighter green in color than leaves of plants of the cultivar Red         King.     -   3. Plants of the new Anthurium had smaller spathes and shorter         spadices than plants of the cultivar Red King.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Anthurium, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Anthurium. The photograph comprises a side perspective view of a typical plant of ‘Red Sensation’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar Red Sensation has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following observations and measurements describe plants of the new Anthurium that were grown in containers in Apopka, Fla., in a polypropylene-covered shadehouse with light levels about 2,500 foot-candles. During the production of the plants, temperatures ranged from 15° C. to 40° C. Plants used for the photograph and description were about one year from planting. Color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
